Roll for transferring dyes or the like



Sept. 19, 1933. w. H. HEFFERNAN ROLL FOR TRANSFERRING DYES OR THE LIKE Original Filed May 10, 1930 Patented Sept. 19, 1933 UNITED STATES PATENT OFFICE William H. Heflrcman, North Adams, Mass, as-

signor to Hefiernan Brush Company, Inc., North Adams, Mass, a corporation of Massachusetts Original application May 10, 1930, Serial No. 451,328. Divided and this application January 15, 1931. Serial No. 509,022

1 Claim.

The present application is a division of the one filed by me on May 10, 1930, Serial No. 451,328,

for an improvement in comber rolls for combing raw cotton with brushes secured to the roll. In

5 the parent application, the claims and description are limited to the two part semi-cylinder paper members which are formed with reduced ends and cap pieces which fitonto these ends, the

, cap pieces having openings to receive a supporting and driving shaft.

An object of the present invention is to provide means for attaching the dye transferring roll to a driving or supporting shaft. At the present time, difficulty is experienced in securing and removing the bearing ends to the roll since the rolls which are composed of paper do not furnish sufficient strength for securing a shaft or bearing members thereto. Broadly, the invention comprises a paper tube which is formed of a plurality of concentric or spiral layers of paper.

In the present application, the description,

drawing and claim are limited to the pin construction for securing the metal bearings or stub shafts to the tubular cylinder member of paper which has been. treated with boiled sulphur. Holes are formed near the opposite ends of the roll which pass through the layers or mass of paper and which holes register with recesses or holes in the two metal bearing members. Pins are inserted and driven into these registering holes, whereby the bearing members are firmly secured to the paper tubular members.

It has been found from actual experience that rolls, which are composed of wood, and used in dyes for transferring the coloring material, or

plain run in colors to the printing or other rolls, when,'for example, print cloth is being made, do not retain their true cylindrical or circular shape. This defect, I have successfully overcome by mak- 40 ing the rolls either of wound strips of paper, or molding the same from paper pulp. After the roll is completed, it is subjected to a bath of boiled sulphur. If desired, the paper strip may be so treated before being wound on the mandrel or other tool.

An important feature of my invention is the ease with which the bearing members or stub shafts may be removed and replaced when necessary.

The present roll is rotatively driven in a bath of liquid dyes, or in other words, plain run in colors.

Referring to the drawing:

The figure is a side elevational view, partly in section, showing the pin construction for securing the metal bearings in place in the tubular and cylindrical member of paper.

Referring to the drawing in detail:

1 designates the cylindrical member which is formed either of a plurality of layers of paper 2 of suitable thickness and texture that are spirally wound on a former in any suitable manner, or is molded from paper pulp. They may be treated with any suitable adhesive material before winding. 3 designates the metal bearing or stub-shaft members, the reduced portion .4 being the part which rests in the usual bearing boxes, not shown, when the roll is in use. 5 are pins composed of wood or any suitable material. These pins pass through openings 6 in the ends of the paper tubu-'- lar member, as shown. These pins enter registering openings 7 in the metal bearing members 3 and have a driving fit therein. These pins are flush with the surface of the roll in order that they may not interfere with the colors or dyes.

- The layers of paper, or the roll, as stated, are treated with boiled sulphur or suitable chemicals, 7 in order to render them impervious to the dyes and for the purpose of causing the finished roll to retain its true cylindrical shape, which is not, as stated, obtained with wooden cylinders or rolls when operated in liquid dyes or inks as a plain roll. If desired, I may form the paper roll 1 by molding the same, instead of winding layers of paper.

It will be seen from the description that I have provided a very efiicient and reliable means for securing the bearing members to a paper roll for transferring dyes, or the like, to a printing or other member, also, one that readily permits the bearing members to be readily taken apart and reassembled.

What I claim is:

A device for transferring liquid dyes comprising an open ended'tubular member composed of layers of paper which has been treated with boiled sulphur, said member having openings extending through said layers, a bearing member insertable into each of the ends of the tubular member and having openings therein, removable pin means located in the openings of the. tubular member and the openings of the bearings for securing the bearings to the tubular member.
